Filter chamber's airtight and the pressure difference are two conditions for filter press equipment normal operation.
In addition to filter chamber is a little special for filter press equipment, the rest of the accessories are generally able to run normally.
Only filter chamber is organic arrangement by separate filter plate and filter cloth, at the same time must be under enough pressure to form filter chamber, a large number of filtrate will leakage from the gap if the filter chamber can’t afford the counter-acting force from filtrate, that the filtrate will not through the filter cloth, the filtrate which not through the filter cloth can’t occur natural separation of solid and liquid, that the most basic function of the pressure filter can’t be achieved.
So the necessary condition is that the filter chamber airtight.
In addition to need airtight filtering structure and both sides of filter cloth need to form pressure difference.
When the filtrate in under the action of the pressure difference, from a high pressure environment to a low pressure environment, which provides a power of the movement for liquid, coupled with the effects of the filter cloth that liquid has the power to wear filter cloth and dialysis out, which can’t wear filter cloth solid intercepted on the other side of the filter cloth.
If no pressure difference formed on the both sides of filter cloth, filtrate will not separate even if contact with the filter cloth, so the pressure difference is a necessary condition for equipment work.
To understand the working principle of filter press and operation specification, which is the first step in right operating equipment.
